Title: 1000s schematics and tips
Post by: dai on July 27, 2002, 12:41:00 am
Hello! I am a 1000s owner, and I want to know where I can found the schematics. I want to know the differences between 2000s and 1000s, too. I will appreciate your help. My trebble pot doesn´t works, (or the change is too little) what could be the problem? thanks your very much!

please! email me: dsotile@fusionactiva.com.ar

From your treble pot description I am assuming that there is no increase in treble as you rotate the control clockwise.

One of the side lugs of the treble pot will be connected to a capacitor... a value of either 270pf or 470pf - Sunn used both and I don't have a 1000s schematic to tell you the exact value.  Chances are pretty good it will be a ceramic type of capacitor, rated at least 400 volts or higher, probably light tan in color.

This cap is either bad, or there is a bad solder joint, or the connection has been broken on either side of the cap.
